This study presents an optimized and validated HPLC-DAD method for quantifying steroidal glycoalkaloids (α-solanine and α-chaconine) in potato tubers. The method was applied to potato breeding lines to assess genotype-dependent variations, providing a sustainable analytical tool for food safety monitoring and potato breeding programs.
This study evaluates the pathogenicity of twelve fungal isolates associated with dry rot on cold-stored potato tubers in Korea. The researchers identified various Fusarium species and Clonostachys rosea as causal agents of rot under low-temperature conditions. These findings highlight the need to consider both major and opportunistic fungal pathogens when managing postharvest potato dry rot.
This study investigates the use of wild potato volatiles to deter oviposition by the potato tuber moth (Phthorimaea operculella), a major potato pest. By comparing wild and cultivated potato varieties, the researchers identified specific volatile compounds, such as benzaldehyde and γ-terpinene, that repel gravid moths and deter egg-laying. These findings highlight the potential of wild potato genetic resources for developing pest-resistant varieties and integrated pest management strategies.
This study characterizes how the effector AVRcap1b from the potato late blight pathogen Phytophthora infestans suppresses host immunity. The researchers show that AVRcap1b interacts with the host protein TOL9a and the helper NLR NRC2 to inhibit immune signaling. These findings reveal a novel mechanism of pathogen-mediated immune suppression, which is highly relevant to engineering late blight resistance in potatoes.
This study reveals how the effector AVRcap1b from the potato late blight pathogen Phytophthora infestans suppresses host immunity by blocking the assembly of a helper NLR resistosome. By structurally characterizing the interaction, the researchers show that the effector stabilizes a stalled intermediate of the immune receptor. These findings provide crucial insights into the molecular mechanisms of potato pathogen virulence and host immune evasion.
This study identifies and characterizes stress-responsive chitinase genes in potato under drought and disease conditions using RNA-seq, molecular docking, and qRT-PCR. The findings reveal distinct expression patterns and binding affinities among different chitinase classes, highlighting their roles in potato defense mechanisms and abiotic stress tolerance.
This study evaluates the use of ozone-modified potato starch combined with κ-carrageenan as a gelatin alternative in dairy desserts. The researchers optimized the formulation to achieve textural, sensory, and rheological properties comparable to gelatin-based controls. The findings demonstrate that modified potato starch can serve as an effective, environmentally friendly gelling agent in food science applications.
This study evaluates extraction methods for potato trypsin inhibitor (PTI) from processing wastewater, identifying acid precipitation-salting out as the most effective technique for achieving high purity and functional stability. The research highlights the potential of PTI as a bioactive ingredient, contributing to the sustainable valorization of potato-derived industrial byproducts.
This study investigates the optimization of LED lighting parameters to improve potato minituber production in controlled environments. It integrates physiological yield assessments with molecular analysis to understand the genetic or metabolic responses of potato plants to specific light spectra.
This paper examines the long-term impact of intensive agricultural selection and genetic improvement on the nutritional composition of various crops, including potatoes. It highlights a potential 'dilution effect' where increased yields correlate with declines in certain micronutrients, providing important context for future potato breeding and functional genomics research.
